Abstract

Wildlife's role in the spread of antibiotic resistance has received insufficient attention. We report the first meta-analysis and systematic review in analyzing the prevalence of Vancomycin-resistant Enterococcus in wildlife. Databases such as, PubMed, Scopus and Google Scholar were searched. Data was extracted by two independent reviewers and the results were reviewed by a third. Two reviewers independently assessed the study protocol using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist and the study quality using the Joanna Briggs Institute (JBI) critical appraisal checklist for prevalence data. Comprehensive meta-analysis version 2 was used for the meta-analysis. The random effect model was used, publication bias was assessed using the Eggers test, funnel plot and the Trim-and-Fill method. Sources of heterogeneity were analyzed using the leave-one-out meta-analysis, subgroup analysis, and meta-regression. Twenty-five studies met the eligibility criteria, but because a study reported the prevalence of VRE in more than one type of wildlife, they were considered as individual studies and 26 studies were therefore added to the final meta-analysis. Of the 3845 isolates tested in the included studies, 312 were VRE. The pooled prevalence of VRE in wildlife was estimated at 6.6% (95% CI; 4.0–10.5%; I2 = 93.011%; P < 0.001). Between-study variability was high (t2 = 1.519; heterogeneity I2 = 93.011% with heterogeneity chi-square (Q) = 357.717, df = 25, and P < 0.001). The funnel plot showed bias which was confirmed by Egger's test (t -value = 4.850; P = 0.00006), and estimates from the leave-one-out forest plot did not affect the pooled prevalence. Seven study was missed and fall at the right side of the pooled estimate by the Trim-and-Fill method. Pooled prevalence of VRE in wild mammals and wild birds were 6.9% (CI=3.7-12.5%) and 6.3% (CI=3.0-12.7%) respectively. More studies were reported from Portugal with a pooled prevalence of 5.0% (CI; 2.8-8.8%). Agar dilution and feces were utilized most in the detection and sampling of VRE respectively. Only sample type (P = 0.04) is a predictor of heterogeneity among the variables. Increased surveillance of VRE in wildlife is required. [ABSTRACT FROM AUTHOR]

47. Multi-model assessment of global hydropower and cooling water discharge potential under climate change.

Abstract

Worldwide, 98% of total electricity is currently produced by thermoelectric power and hydropower. Climate change is expected to directly impact electricity supply, in terms of both water availability for hydropower generation and cooling water usage for thermoelectric power. Improved understanding of how climate change may impact the availability and temperature of water resources is therefore of major importance. Here we use a multi-model ensemble to show the potential impacts of climate change on global hydropower and cooling water discharge potential. For the first time, combined projections of streamflow and water temperature were produced with three global hydrological models (GHMs) to account for uncertainties in the structure and parametrization of these GHMs in both water availability and water temperature. The GHMs were forced with bias-corrected output of five general circulation models (GCMs) for both the lowest and highest representative concentration pathways (RCP2.6 and RCP8.5). The ensemble projections of streamflow and water temperature were then used to quantify impacts on gross hydropower potential and cooling water discharge capacity of rivers worldwide. We show that global gross hydropower potential is expected to increase between +2.4% (GCM-GHM ensemble mean for RCP 2.6) and +6.3% (RCP 8.5) for the 2080s compared to 1971–2000. The strongest increases in hydropower potential are expected for Central Africa, India, central Asia and the northern high-latitudes, with 18–33% of the world population living in these areas by the 2080s. Global mean cooling water discharge capacity is projected to decrease by 4.5-15% (2080s). The largest reductions are found for the United States, Europe, eastern Asia, and southern parts of South America, Africa and Australia, where strong water temperature increases are projected combined with reductions in mean annual streamflow. These regions are expected to affect 11–14% (for RCP2.6 and the shared socio-economic pathway (SSP)1, SSP2, SSP4) and 41–51% (RCP8.5–SSP3, SSP5) of the world population by the 2080s.
